Additionally, "Tu Feng" (earth bee) is also a type of bee. *Erya* states: Regarding "Tu Feng", Guo Pu comments: "The large bees of Jiangnan today." Those that build nests underground are called "Tu Feng"; those whose larvae are consumed are hornets (*Ma Feng*), referred to in the Jing-Ba region as [missing character]. There is also "Mu Feng" (tree bee); Guo Pu comments: "Similar to Tu Feng but smaller, building nests on trees, also called Mu Feng in Jiangdong," and its larvae can be eaten. *Liji · Tan Gong* states: "Fan" refers to the cap. Zheng Xuan comments: "Fan" means bee. *Fangyan* states: In the Yan-Zhao region, bees are called [missing character]; the small ones are called [missing character] or You Tui; the large ones that produce honey are called Hu Feng.
